(KAEŴṚff) Figs 19–21 Type material. Holotype ♁, CHINA : Yunnan Province : Hani-Yi Autonomous Prefecture of Honghe , Pingbian Miao Autonomous County , Daweishan National Forest Park ( 22°54.317′N , 103°41.961′E , 2124 m a.s.l. ), 28 Oct. 2016 , leg. Yannan Mu. Paratypes : 4 ♁ 5 ♀ , with same data as holotype . Etymology. This species name is a combination of “ allocot ” and “ manubrium ”, referring to the long pedicel; adjective. Diagnosis. This new species resembles O. taoyuan ( Fu, Chen & Zhang, 2016 ) in having a similar femoral apophysis, but can be recognized by: 1) slender embolus (vs short and thick, cf. Fig. 20C and figs 9B, 10B in Fu et al. [2016]), 2) shorter retrolateral tibial apophysis without distinct curvature (vs long and curved tip, cf. Figs 20B, D and figs 9E–F, 10C in Fu et al. [2016]), 3) curved tip of dorsal tibial apophysis (vs not curved, cf. Fig. 20B and figs 9F, 10C in Fu et al. [2016]), 4) digit-shaped glandular appendages (vs absent, cf. Fig. 20F and figs 9H, 10E in Fu et al. [2016]), and (5) closely situated spermathecae (vs separate, cf. Fig. 20F and figs 9H, 10E in Fu et al. [2016]). Description.
